The invention discloses an externally meshing paper roll clamp. A swing gear (3) of the externally meshing paper roll clamp is of an external tooth structure and compassed of an inner ring and an outer ring. Steel balls are installed between the inner ring and the outer ring, and the inner ring and the outer ring rotate relatively. The inner ring is fixed to a rear base plate assembly (12). A gear on the outer ring meshes with a speed reducer (54) of a hydraulic system, namely the swing gear (3) meshes with the reducer (54) in an externally meshing mode. The externally meshing paper roll clamp has the advantages that the swing gear meshes with the reducer in the externally meshing mode, so that the horizon is greatly improved, and the requirement for the torque of a hydraulic motor is low.
